OK, I am going to set aside your first sentence.
Response to second: Well, maybe not, there can be phenomenally formless and noumenally formless.
This is within Kantian language, and this is one of the disputes that Nietzsche had with him … trying to slip God in the back door. (i.e., the noumenal is not perceptible, which is why we end up with this cliched protestant interpretation of Kant “by faith alone.”) I reserve opinion, but Spinoza definitely advanced immaterial mind (i.e., the formless or immaterial God - thought and extension - “in” our minds). Active spirit, or if you want to say force, meaning, roughly, the power to affect and be affected.
So, an aside: speaking of taking in sensory data (which means what? bits of information? hmm), and making sense of it, for me, this framework is too Kantian, because it assumes that human sense is passively receptive. It seems to me, especially with this talk of kamma, cetana, etc. going on, that Buddha was aware of a much more active, relational condition “of” “in” “to” ? perception.
So, if we cede that formlessness is a real experienced condition, meaning it can be perceived, because we have introspection - mind is active and sensing - well, what would it be …to perceive formlessly in a way that could be useful (delicately predicated) for dhamma?
Now, we have a strong visual bias in Western society.
And, also speaking of Christianity, “logos” means word, but it also means Christ. God made flesh in the Word is one way to look at our baby Jesus, (which I am now making certain connections to Scholasticism), but anyway, we are so extraordinarily tied to belief in language = the ontic in terms of human being (our covenant with God? OK, anyway).
We have to push back on that and take that we have precognitive abilities (of our own??). We’re not just a bunch of passive humours, so to speak, until some kind of mechanical entrapment brings us into coherent, articulate being, and then we have to set about cleaning out the mess.
We are active beings in a good, healthy, free way. This is one of the things that separated Kant from all the rest; he believed humans are good. Certain conditions apply, obviously, finding them is what matters. (Then you have Kierkegaard with the Call, and we move into the domain of Calvinist rapture. So let’s stop.)
What I like about Buddhist understanding of sense is body consciousness. We superficial people emphasize “touch” or “taste” or “odour,” which is the surface. But we actually have haptic sensibility (which I think still means touch, but is interpreted differently). We even have expressions for it, we think with our gut, for instance, feel it in our bones.
The formless world is a notable attainment, right? I don’t think it’s easy to attain, right? But the point is, if you got it, and it was within, right view, proper understanding, it could be something on the path. It doesn’t have to be necessary, but if you were a practitioner of visualization meditation, you would have to go through haptic sense. And this includes of the mind.
I think it’s clear. The outcome isn’t noumenal, right?
